hello Aspirant,

you don't need to worry about age for Engineering entrance examination because there is no age limit to sit in the entrance exam of JEE. You just need to complete your 10+2 with math's and Physics as a compulsory subject to grab a seat in Indian Institute of Information technology, Allahabad (IIIT Allahabad). Just try to score better in JEE mains specially, don't worry about Advance because you can get into any IIIT or NIT only by clearing JEE mains, hope this will work.

Best of luck!!!
